To albgwlwrai, it may concern.-

Be itkiiown that 1, Louis GoDDU, of'Win chester, county 01' Middlesex, andState of Massachusetts, here inventcdian Improvement in, lioot and Shoe N ailinglllachines, of which the following description, in conncctiouwith the accompanying drawings, isa. specification, like letters on the drawings representing like parts.

This invention has for its. object to improve that class of nailing-machines wherein pieces 01' wire are cut off in succession from a long length of wire, preferably in coil form, the said pieces so out ofl varying in length according to the variations in thethiekness of the stock between the nose and born or anvil,

the said pieces being pointed and headed to form nails 0f the length required for the stock resting on the usnal horn or anvil, in which stock the next nail is to be driven, my present invention being an improvement on the machine described in United States Patent No. 215,117, dntedMey 6, 1879.

One of the features of my present invention relates to the clamping-dies for holding the wire at one .point while the wirejust above. the said dies istbeing cut and headed, the said clamping-dies, "thehead-forming portion of the nail next to be driven having been iijiade, beingmoved snflicijently to complete the sep aration of the nail from the main body efzthe wire and transfer it into position under the driver to be. driven, the separation of the nail from the wire leaving the end of the point at 7 right angles to the body of the nail, thus'insnring a point which will drive withoutglanc- Another portion. of my invention includes the combination,. with clamping-dies, of a circularly-moviug header, which cuts into and partially severs the wire in the processes of upsetting the head, the said header serving the further purpose of holding the wire firmly at what is to be the point of the'next nail, while the clamping-dies referred to, by their hori zoutal movement, complete the severance of the headed nail from the wire.

My invention alsoconsist-s in the co1nbinasen-tn No. 211,013. (No model.)

tion, with the mainshaft, its friction or clutch pulley, the cam for actuating the feeding do vices for the wire, and the cam-slide l'or forcing the two parts of the pulleyin d['lVillg-C()lltact, of a, com to control the point at each rotation of the said main shaftgit which its rotalion may be stopped, theinachine being L thereby stopped in such positions that the larger part of the said feeding-cam is in operative position with relation to the feeding mechanism, holding the same in the position from which it is to start to move forward, as will be described.

The mechanism just referred to by its use insures the feeding oi'the wire only by its actuatingcairi and prevents the same being fed by the action of the horn through the measuri ing devices between it and the feed-roll.

Figure 1 in front elevation, partially broken out, shows a suflicient portion of the head of a nailing-machine embodving my present invention to enable'the sam .5 to be understood, '70 the usual column on which the head stands being omitted. Fig. 1 shows the stud on which the 'feed-wheel turns; Fig. 1 a detail of the awl-bar and the segmental lever for actuating it; Fig. 2, a right-hand side elevation thereof, withthe clutch-pnlley and part of the frame broken out; .Fig. 3, a detail showing the cam and'thewedge actuated byit. Fig. 4 is a detail showing the clamping-dies, the header,

andother-parts, to be described, immediately back of the throat-plate, which acts asa guide for the aw], the front cap forming part of the wire-passage being also omitted to show a part of the wire-passage and the die therein at its lower end.

' 'eTh'e head A oi-framework of the machine will in practise be niounted upona column, as in the patent referred to. This'h'ea'd contains bearings for the main shaft A", having*fast on; it the part A of the clutch or'l'rictionfl-pu'liey, the other part, A being loose on thesaid main shaft. The loose part A? has a long hub (see l ig.' 2) where the pulley is.-bro ken out, on which is mounted, loosely a sleeve, alsljabbd at its sides, as best shown bydotted lines in Fig. 3, the said sleeve being embraced by a forked part of a slide-bar, Aflhaving at oneside a wedge, a, the inclined face of which arts against correspondingly-inclined shoullets of the said sleeve in'the upward move; ment of the slide-bar A,.itii1'-practice being attached at its lower end to'a rod jointed'to'therear end of a treadl'e pivoted to th'embas'e 0f the machine in usual manner. g The siidebar A" at its upper end'fca'r'riesan eccentric-roll, a", having a handle, a by which it may be turnedv to place the face of .thasa'id roili'o'lttfiof the range of the cam A when'it is desired that the inain shaft be rotated by hand, as'when'adjusting the'lhachine or the operatbr is ettiug ready for work.

or other stud, 0", {see dotted lines, Fig. 2,) which enters the-cam groove 14 (shown by dotted lines,"Fig. 6) at the rear'side of the camwheel-C. The clamping-die is composed of two parts,fg, (best shown in the detail, Fig;

5,) the partf being carried by a slide bar, f, while the part 9 is carried by a slide-bar, g, the two parts, when broughttogether as shown in Fig. 5, leaving a space, as 2, in which may enter the wire w. The part ghas a shoulder, 8, (see 5,) in order that when the partf' is moved positively in the direction of the arrow upon it (see Fig. 5) the part 9 will be moved in the same direction with the part f. The bar f is toothed, as shown at f", and is engaged by the toothed sectorf at the lower end of an arm or lever, f*, pivoted at f and provided at its up per end with a roller or other stud, asf, which enters the grobve f in the cam B.

lhe lcverfat its lower end has pivoted to it in the pitch line of the teeth of the sector f a locking device, h, herein shown, as a hook havii'ig a cam-face, the said' locking device having extended through it a controlling rod, h, by which the locking device may be moved at the proper time to engage it with or disen' gage from a roller or other stud, h", on the bar The controllingrod h is loosely jointed to .one end of a lever, h, (see Fig. 8,) pivoted at h, and provided at its other end with a frictionroil, 7fi','which is acted upon'bya spring, h, to engage the hook with the stud If, the

said hook being lifted positively bythe pcriphery of the cam B.

The controlling-rod few" carries loosely upon ends, which bear, respectively, upon the rounded, eonvexed, or ball-like upper side of the locking device, and a like surface, If, of the lever h, the rod also having upon it a loose washer, If, and a collar, h both concaved, and a spring, h", and auadjusting-nut, h, the said sleeve-and the spring and the parts described obviating any lost motion in the locking device. The force of the spring h is made adjustable by the until;

Fig. 4 shows the wire channel 8, through which the wire is fed. At the lower end of this channel I have placed a point-forming die, in, made adjustable as to its position by means of a screw, in", the inner end of the said die having a groove, 7, (see Fig. 10,) the shape of onehalf the point of the nail.

Fig. 5 shows the clamping-dies as opened in the position that the dies will occupy when wire to is to be fed from the feeding'channei. 8 into the space 2 between the clamping dies, the end of the bar g at such time resting againstan adjustable stop-screw, 18, the header cat such time being in the position in Fig. 4,

. or elevated. The wire to having been fed into the said space 2, the cam. 13 in its further r0- talion in the direction of the arrow, Fig. 2, causes the lump 16 (see 7) to act upon the 'it a sleeve, If, having rounded or concaved lever f and draw the bar f in the direction of the arrow upon it in Fig. 5, th d's effectually clamping the wire w between the diesfg, the

- faces of the dies being suitably corrugated, if desircrhto corrugate the body of the wire now to be made into a nail. The end of the wire having been firmly clamped,.the rock-shaft c is moved so that the portion 4 of the header 0, it moving in the are of a circle, contacts with the wire 1'0 in the space 7 at the inner end'of the pointformiug die at, and the corner 4 of the header cuts into thewire in-a circular direction and pushes in'advancc of it a portion of the wire down toward the clamping-diesf thus forming a head, the portion of the wire next above the head so formed, andto constitute the pointof the nail next to be made, remaining in the recess 7 of' the pointiorming die m, and between it and theperiphery of the said header, which at such times holds the wire firmly at the junction of the head and point referred to. In this condition the cam B, the hooked part of the locking, device h having been thrown down to engage the stud h" about'as the head was formed, acts to turn the lever-f so thatit, by its teeth in engagement with the barf and by the hooked looking de,vice, positively movesthe said die-hold ing'vbarsforward in unison, firmly clamping and carrying with it the nail, the said dies at such ti me moving horizontally away from the point-forming die and header, the header remaining in position until the wire is severed, the jaws continuing to' move and to hold the nail clamped until the nail has been placed nearly in the line of descent of the driver, when the locking deviceh is lifted from the stud h", thus releasing thebarg from pressure andpermitting it to immediately come to rest by reason of the friction device n in contact with it, the barf having given to it a slight. forward movement, the dies at the time the nail arrives directly under the driver being in position to leave s'nt'licient space for the'entrance into the die of the driver to enable it to drive the headed nail from the dies out through the throat-passagec into the stock on the usual horn. (Not shown.) The nail having been driven, the awl descends into the stock to feed the stock, the driver comes up and remains up, and the awl comes up, and at the same time the dies are rct-ract-edby the leverf", the die-barf starting first and moving until a corner thereof meets ad shoulder, 3, of the dieg, when both dies thereafter move back together until the rear end of the die-bar g meets the stop 18, referred to, when the diebarf is again given a slight forward movcment,wl ile the die-bar g is held friotionally, the movement bei rig suiiicient to open the dies, asbcforc stated, for the entrance of the wire. as in Fig. 5. The friction device n,.which acts against the die-carrying bar g", consists of a block ex tended through a slot in. the rearend ofa bar,
